ABSTRACT:
An optical element is formed by co-extruding to have an arrangement of polymer scattering fibers within a polymer matrix. The scattering fibers lie substantially parallel to a first axis. The scattering fibers are arranged at positions across the cross-section of the polymer matrix to scatter light transversely incident on the optical element in a direction substantially orthogonal to the first axis. The positions of the scattering fibers across the cross-section of the optical element may be selected so as to form a two-dimensional photonic crystal structure for light transversely incident on the optical element.
